Objective: To investigate the risk factors for the development of deep infiltration in early colorectal tumors (ECT) and to construct a prediction model to predict the development of deep infiltration in patients with ECT. Methods: The clinicopathological data of ECT patients who underwent endoscopic treatment or surgical treatment at the Cancer Hospital, Chinese Academy of Medical Sciences from August 2010 to December 2020 were retrospectively analyzed. The independent risk factors were analyzed by multifactorial regression analysis, and the prediction models were constructed and validated by nomogram. Results: Among the 717 ECT patients, 590 patients were divided in the within superficial infiltration 1 (SM1) group (infiltration depth within SM1) and 127 patients in the exceeding SM1 group (infiltration depth more than SM1). There were no statistically significant differences in gender, age, and lesion location between the two groups (P>0.05). The statistically significant differences were observed in tumor morphological staging, preoperative endoscopic assessment performance, vascular tumor emboli and nerve infiltration, and degree of tumor differentiation (P<0.05). Multivariate regression analysis showed that only erosion or rupture (OR=4.028, 95% CI: 1.468, 11.050, P=0.007), localized depression (OR=3.105, 95% CI: 1.584, 6.088, P=0.001), infiltrative JNET staging (OR=5.622, 95% CI: 3.029, 10.434, P<0.001), and infiltrative Pit pattern (OR=2.722, 95% CI: 1.347, 5.702, P=0.006) were independent risk factors for the development of deep submucosal infiltration in ECT. Nomogram was constructed with the included independent risk factors, and the nomogram was well distinguished and calibrated in predicting the occurrence of deep submucosal infiltration in ECT, with a C-index and area under the curve of 0.920 (95% CI: 0.811, 0.929). Conclusion: The nomogram prediction model constructed based on only erosion or rupture, local depression, infiltrative JNET typing, and infiltrative Pit pattern has a good predictive efficacy in the occurrence of deep submucosal infiltration in ECT.

Objective: To observe the effect of cancer nursing plan based on risk concept on complications, self-care ability and quality of life of patients with cervical cancer undergoing radiotherapy. Methods: Totally 68 patients with cervical cancer undergoing radiotherapy from February 2016 to February 2018 were included in the study. According to the random method of drawing lots, they were divided into two groups, 34 cases each. The control group was given routine nursing intervention, while the observation group was given cancer nursing plan based on risk concept. The intervention time was from the day of admission to the end of discharge. Comparing the incidence of complications between the two groups, the self-care ability implementation scale and the Chinese version of the World Health Organization quality of life scale were used to evaluate the self-care ability and quality of life before and after the intervention. Results: The incidence of complications was 14.70% (5/34) in the observation group and 38.23% (13/34) in the control group, with statistically significant difference (t=4.836, P<0.05).Before intervention, there was no significant difference in scores of each sub-item and total score of self-care ability implementation scale between the two groups (t=0.336-1.224, P>0.05). After intervention, the health knowledge level, self-concept, self-responsibility, self-care skills and total score of the observation group were (48.37±4.10), (27.56±4.12), (26.56±5.09), (29.54±5.87), (132.02±19.15) points, respectively. After intervention, the scores of the above dimensions and the total scale in the control group were (44.10±3.74), (24.16±3.47), (20.40±4.12), (24.13±3.65) and (112.78±14.97) points, respectively, with statistically significant differences (t=3.680-5.485, P<0.05). Before intervention, there was no significant difference in sub-item scores and total scores of QOL between the two groups (t=0.151-0.996, P>0.05); After the intervention, the observation group physiological, psychological, social relations, the environment and total score of (24.85±2.63), (21.34±2.73), (20.76±2.47), (19.07±2.45), (86.02±10.27) points and the control group was (19.09±2.03) points, (17.65±2.13), (17.29±2.30), (16.38±2.37), (70.41±8.82) points, the difference had statistical significance (t=4.601-10.109, P<0.05). Conclusion Tumor care plan based on risk concept can reduce the incidence of complications related to radiotherapy for cervical cancer patients, and improve their self-care ability and quality of life.

Source identification of human biological materials in crime scene plays an important role in reconstructing the crime process. Searching specific genetic markers to identify the source of different human biological materials is the emphasis and difficulty of the research work of legal medical experts in recent years. This paper reviews the genetic markers which are used for identifying the source of human biological materials and studied widely, such as DNA methylation, mRNA, microRNA, microflora and protein, etc. By comparing the principles and methods of source identification of human biological materials using different kinds of genetic markers, different source of human biological material owns suitable marker types and can be identified by detecting single genetic marker or combined multiple genetic markers. Though there is no uniform standard and method for identifying the source of human biological materials in forensic laboratories at present, the research and development of a series of mature and reliable methods for distinguishing different human biological materials play the role as forensic evi-dence which will be the future development direction.

OBJECTIVE: To explore the effects of UVB and Nano-CaCO_3 co-treatment in inhibiting cell proliferation and inducing cell apoptosis in human HaCaT keratinocytes,and to explore its possible mechanisms. METHODS: HaCaT cells( logarithmic growth phase) were divided into control group,UVB group,Nano-CaCO_3 group and co-treatment group. UVB group and co-treatment group were irradiated with UVB irradiation with cumulative exposure dose of 2. 97 × 10~(-2)J / cm~2.Control group and Nano-CaCO_3 group were irradiated with UVB irradiation with cumulative exposure dose of zero on equal terms. After that,control group and UVB group were treated with 10. 00% phosphate buffer solution in high-sugar Dulbecco's modified Eagle's medium( DMEM) and incubated,Nano-CaCO_3 group and co-treatment group were treated with high-sugar DMEM with Nano-CaCO_3 at 250 mg / L mass concentration and incubated. Subsequently,HaCaT cells were harvested at incubation time of 0,6,12,18 and 24 hours. Then methyl thiazolyl tetrazolium assay was performed to estimate cellular proliferative activity,flow cytometry was used to detect cell apoptosis,Western blot was used to detect the expression of P53 and Caspases-3 protein. RESULTS: Contrast to control group at the parallel incubation time points of 6-24 hours,the cell viability of HaCaT cells was significant decreased in the other three groups( P < 0. 05) except for UVB group at incubation time of 6 hours( P > 0. 05). The cell viability of co-treatment group was lower than UVB group at all the incubation time( P < 0. 05),and lower than Nano-CaCO_3 group at incubation time of 18 and 24 hours( P < 0. 05).The apoptosis rate of HaCaT cells in UVB group was higher than control group( P < 0. 05),and which in co-treatment group was higher than the other three groups( P < 0. 05). Contrast to control group,the protein expressions of P53 and Caspases-3 in HaCaT cells were upregulated in UVB group and Nano-CaCO_3 group. In co-treatment group,the protein expressions of P53 and Caspases-3 were upregulated contrast to the other three groups. CONCLUSION: Contrast to single damage of UVB or Nano-CaCO_3,co-treatment of UVB with Nano-CaCO_3 increased damage to HaCaT cells,likely by inhibiting proliferative activity,inducing apoptosis,and enhancing protein expressions of P53 and Caspases-3.

BACKGROUNDChromosomal abnormalities have been shown to play an important prognostic role in multiple myeloma (MM). Interphase fluorescence in situ hybridization (i-FISH) has been much more effective to identify cytogenetic aberrations in MM than conventional cytogenetic technique (CC). To clearly determine the cytogenetic features of Chinese MM patients and identify their prognostic implications, we designed a multicenter study based on i-FISH including 672 patients from 52 hospitals in China.

METHODSAll 672 patients were systematically screened for the following genomic aberrations: del(13q), IgH rearrangement, del(p53) and 1q21 amplifications.

RESULTSThe analysis showed that the chromosomal changes were detected in 22.1% patients by CC and in 82.3% patients by i-FISH. The most common abnormalities by CC were chromosome 1 aberrations (48.4%), -13/13q- (37.6%), hyperdiploidy (36.6%), hypodiploidy (30.1%) and IgH rearrangements (23.7%). The most frequent abnormalities by FISH was del(13q), which was found in 60.4% patients, whereas IgH rearrangement, 1q21 amplification and p53 deletions were detected in 57.6%, 49.0% and 34.7% cases, respectively. By statistical analysis, -13/13q- by CC was associated with low level of platelet (P = 0.015), hyperdiploidy was associated with low level of serum albumin (P = 0.028), and IgH rearrangement by FISH was associated with high level of β2 microglobulin (P = 0.019). Moreover, 1q21 amplification and del(p53) by FISH conferred a high incidence of progressive disease (PD) after initial therapy. Metaphase detection of IgH rearrangements and chromosome 1 aberrations concurrently was associated with a short progression free survival (PFS) (P = 0.036). No significant prognostic implications of other cytogenetic abnormalities were found associated with overall survival and PFS.

CONCLUSIONSChinese MM patients had similar cytogenetic abnormalities compared with the previous reported studies. However, the prognostic significance of FISH aberrations were not clearly determined and further study is required.
